Long-term Clinical Outcomes of One-Stage Cartilage Repair in the Knee With Hyaluronic Acid–Based Scaffold Embedded With Mesenchymal Stem Cells Sourced From Bone Marrow Aspirate Concentrate

Abstract

Repair of full-thickness cartilage injury in the knee with a HA-BMAC provides good to excellent clinical outcomes at long-term follow-up in the treatment of small to large lesions. Cartilage repair with HA-BMAC leads to comparatively successful long-term outcomes in the treatment of small or large lesions, single or multiple lesions, and lesions in 1 or 2 compartments, as well as in cases of associated lesion treatment. While good outcomes can be expected among treated patients >45 years of age, outcomes may be comparatively more successful in younger patients.
